Joint Knowledge: The Elbow

The elbow joint connects the upper arm and the forearm. It is one of the body’s most frequently used joints, and many important structures pass through or around it. The elbow contains a large amount of lubricating liquid (which is, sadly, not called elbow grease). This lubricant allows the elbow to make smooth, precise movements even when it is bearing a substantial weight load.

Joint Knowledge: Bone Mineral Density

Bone mineral density (BMD) is the mass of bone mineral per volume of bone tissue. A BMD test, also known as a bone mass measurement test, is used to gauge a person’s risk of developing osteoporosis and bone fracture. Read on to learn more about BMD and the benefits and risks of getting a BMD test.

Joint Knowledge: The ACL

ACL injuries are among the most common types of knee injuries, usually occurring during activities that require sharp turns, high-impact jumping and landing, physical force to the knee, and sudden stops and starts. These include sports such as basketball, soccer, football, tennis, skiing, and mixed martial arts.

In today’s post, we’re going to take a closer look at this little ligament.

Joint Knowledge: The Knee

The knee is the largest joint in the human body, comprising of four bones, four main ligaments, two main  tendons, and cartilage. It supports the weight of the body and functions as a hinge, allowing lower leg movement. Crucial movements such as standing, walking, running, and squatting rely on healthy knees.

Read on to learn about the structure and function of the knee.

Joint Knowledge: Cartilage

While most think of cartilage as the connective tissue in joints or the lobes of your ear, it is also found in your nose, spine, and trachea.

Cartilage is made up of proteins and water. In fact, it can be up to 80% water, but can diminish with age, when dehydrated, or when a daily diet lacks nutrients that support cartilage health.

Proteins give cartilage its shape and the properties necessary for its function in the body. Together, proteins are often referred to as a matrix, as they form a mesh or webbing.
